- I have no idea what Chrome Frame support is. I've used Google Sites with Chrome and didn't notice anything out of the ordinary.
- An improved UI for inserting stuff is a nice touch, but hardly something I griped about.
- The effect of anonymous Apps Scripts eludes me, but then again I'm not much for jumping in Google Apps API or anything (more designer than programmer).
- More webfonts...I think they are referring to the webfonts release earlier this month.
